Ben Affleck explains why he almost said no to 'Batman'

Ben Affleck took some convincing to accept the role of the caped crusader in "Batman v Superman: Dawn of Justice." 

During an appearance on Thursday's "Conan," the actor described his first reaction to receiving the phone call from director Zack Snyder. 

When he was thinking the movie would portray the superhero's origin story, Affleck said, "I'm not that Batman."

But Snyder's description changed his mind.

"Zack was like, 'No, no, no. This guy's older and he's really f--ked up and he's broken down and he's on the edge of moral bankruptcy,'" Affleck said.

"I'm clearly your man. Say no more," the actor joked. 

Affleck said he was excited to portray the Frank Miller version of Batman.

As for his Superman costar, Henry Cavill, Cavill missed his initial call for "Man of Steel" because he was playing "World of Warcraft."
